Are the vernal equinox, summer solstice, autumn equinox and winter solstice the same in the southern hemisphere and the northern hemisphere? If not, please write down the date.

No, the seasons in the northern and southern hemispheres are opposite, and so are the solar terms.

Northern Hemisphere: vernal equinox (around March 2 1), summer solstice (around June 22), autumn equinox (around September 23), and winter solstice (around February 22, 65438+).

Southern Hemisphere: spring equinox (around September 23rd), summer solstice (around February 22nd, 65438+), autumn equinox (around March 22nd, 2 1), and winter solstice (around June 22nd).
